To all 'whom 'it concern: v

Be it known that I, JoHN H. Ru'rrinnrono, citizen of the United States,` residing at Knoxville, county of Knox, and State of Tennessee, have invented certain new and novel and improved arrangement of lubri eating chamber and ducts whereby both the wheel hub and the'bearing in the pedestal are lubricated.

Other and further objects and advantages of the invention will be hereinafter full7 set forth and the novel features thereof de fined by the appended claims.

In the drawing r-Figure 1 is a vertical section on the line 1-1, Fig. 2; Fig. 2 is a similar view on `the line 2v2, l? ig. l; Figa 3 is a detail perspective of the spring forthe oil cup caps, and Fig. 4 isa similar view of one of the locking keys.

Like numerals refer to like several figures of the drawing.

The numeral 10 designates the axle which may be of any desired size or configuration and is provided with a plurality of circumferential grooves 11 at its outer end. This axle is mounted zin the pedestal 12 which is secured in the usual manner to the frame of parts in the the car or vehicle upon which the wheel lis to be applied. The pedestal is provided with the bearing portion 13 and the cutaway poition 111 extending therefrom to- The 'inner end of the pedestal is formed with a seat 15 ada )ted to receive the felt packing 16 to preven the escape of oil therefrom. The outer end of t-lie pedestal isprovided with the enlarged chamber 17 within `which the felt' or fibrous packing 1S isdisposed, and within this packing the extension 19 from the wheel hub 2() projects. y

The wheel 21 is formed'with the usual spokes or arms 22 extending from the hub 20 thereof, and this hub is provided with the oil chamber 23 having extending therefrom the passages 24 which communicate with the grooved portions 11 `of the axle and with the bearing surface 25 of the hub'. This bearing surface is open or cut away at the portion v26 opposite the grooves 11 of the axle '10,y

and extending through the portion 26 is the key 27 which is mounted upon abolt 28. A plurality of these keys arev used, as shown in Fig 2, so as to resist the end strain and to provide a secure locking with the 'minimum depth of groove in the axle so as to prevent weakening the axle by a deep out groove. The keys-27, as shown in Fig.) 4C, are lprovided vvith .a face 29 curved to correspond with the axle face and are supported out of contact with this face'so as to avoid wear incident-,to frictional contact between these parts. The' key is also provided with the eye 30 to receive thebolt 28 before described.

'This bolt passes through the' wheel hub' in the passage 31 provided for 'that purpose and has a nut 32 disposed uptm its inner end f andv within a recess 33 of the hub extension 19. The opposite end or head of the bolt is in Contact with the packing or gasket 334i and provided with the 'wrench 'hold 35 to' permit its convenient application and removal.

The oil chamber 2B has extended therefrom a series of ducts orpassages 36 inclined toward the center of the axle and passing through tlie"extension so as to discharge into the pedestal and, properly lubricate these parts. fed from the reservoirs 3'1" disposed at opposite sides and between the wheel spokes 22 and thus being in .communication with the chamber by means ofthe passage 38 .leading thereto.. Each-of theboxes is provided with an opening 39 which is normally closed by the -flanged capi 20. This cap is mounted finger hold 42 at one end and secured at its The .oil chamber 23 is' opposite end to theY wall, of the reservoir by means of the bolt e3 oi" other desired means so as to retain the cap under constant tension to prevent-`leakage atjthe opening 39 'which opening .is also provided with the packing or gasket'll to prevent leakage at l`as the key wear thereof by the key-is entirely avoided is pivotally mounted upon its bolt. The construction and arrangement of the oil chamber provides for the thorough lubrication of the axle at all times and also a feed ofoil'to the pedestal, escape of which is effectually prevented by the packings, the outer one of which surrounds 'the wheel ex tension, and the oil passage .therefrom discharges within the pedestal. The construction and arrangement of the reservoirs with the spring closing caps thereof permits a continuous feed to the oil chamber and prevents escape from the boxes while permitting the convenient relling thereof whenever desired.I -The invention` therefore presents a siniple, very efficient and economical construction for attaching a wheel to 'the axle and lubricating these parts in the use oftheinvention. 'Y

l-Ifawdng described my invention and set forth its merits, whait I claimv and desir'e to y secure by Letters Patent is:-

Al. In a device of the class described,`an axle, a pedestal mounted thereon and provided with a lubricating space, a Wheel hav- Aing its hub formed with an oil -chamber an extension from said hub entering said pedestal and provided' with a passage leading from the oil chamber and dischar ing' at its end within the pedestal.

- 2. In a device of the class described, an

therein.

axle, a pedestal mounted thereon and prof ivi'ded with a lubricating space, a wheel having its hub formed with an oil chamberv thereiman extension from said hub. entering said pedestal and provided with a-'passage leading from the4 oil chamber and discharging at the'lubricating space within the pedestal, and a fabric pa-ching disposed at the opposite ends of said pedestal one of which l ing its hub formed with an oil chamber therein, an extension from said hub entering n said pedestal and provided with a passage leading from the oil chamber to the pedestal,

la fabric packing disposed at the opposite ends of said pedestal one lof which surrounds said extension, and o il reservoirs carried` by the Wheel at opposite sides. of said oil chamber and communicating therewith.

4. In a device of the class described, an axle, a pedestal having a .bearing surface therein and lubricating space communicating therewith, a wheel having its'hub -provided with an oilchamber, and an extension laterally from said hub provided with an oil passage from said chamber discharging at the end of the hub within said posite said space. i v 5. In a device ofthe class described, an axle, a pedestal having a bearing and lubrieating space communicating therewith, a wheel having its hub provided with an oil chamber, an 'extension laterally from said hub provided with a passage communicating with said space, a fabric packing disposed within the pedestal and surrounding said hubextension, .and a reservoir communicating with theoil chamber in said hub.

In testimony whereof I affix my signature in presence of two Witnesses.
